The Fakebook link page http://www.skrivarna.com/p/fakebook.html just added scripts to download and index the Creole Jazz Band Fakebooks in C, Bb, Eb and F, as well as in bass clef. These books, originating from http://creolejazzband.com/Fake%20Books.html, contain lots of oldies and goodies shared according to "pay it forward". There are also brand new scripts for the blues classics in the Blues Real Book.
And there's more to come...
Together with the previous resources for downloading and automatic indexing of several Real Books, the Vocal Book, the Slickbook and Django Fakebook, this covers thousands of songs in addition to the 1600 transposable jazz, pop and rock chord charts pre-loaded in the Fakebook app.
